On December 3, 2002, at approximately 18:00 hours (6:00 PM) local time, two witnesses in Annecy, Haute-Savoie, France observed two elongated luminous points moving in a straight line across the sky without any audible sound. The observation lasted approximately five minutes. The witnesses reported the objects maintaining a consistent trajectory and noted the complete absence of engine noise or other acoustic signatures typically associated with aircraft.
GEIPAN (France's official UFO investigation service) conducted a thorough investigation and conclusively identified the objects as the International Space Station (ISS, catalog object 25544) preceded closely by the Space Shuttle STS-113 Endeavour. The shuttle had undocked from the ISS the previous day (December 2, 2002) and was in the process of returning to Earth, with landing scheduled for December 7. Ground track analysis confirmed both objects were visible over the Annecy region between 17:55 and 18:05 local time.
This case represents a textbook example of satellite/spacecraft misidentification and demonstrates how even trained observers can mistake orbital objects for unexplained phenomena when unfamiliar with spacecraft visibility patterns. GEIPAN classified this case as "A" (phenomenon perfectly identified) based on precise orbital data correlation and timeline matching.
02 Timeline of Events
2002-12-02
STS-113 Undocks from ISS
Space Shuttle Endeavour undocks from the International Space Station, beginning its return journey to Earth. This sets up the rare visual configuration of two large spacecraft in close proximity.
17:55
Objects Enter Visibility Range
Both ISS and STS-113 shuttle enter visible range over the Annecy region as they reflect sunlight while passing overhead.
18:00
Witnesses Observe Formation
Two witnesses in Annecy observe two elongated luminous points moving in a straight line across the sky without any sound. They watch the objects for approximately five minutes.
18:05
Objects Leave Visibility Range
The ISS and shuttle pass beyond the visible horizon from the Annecy observation point, ending the sighting.
2002-12-07
STS-113 Landing
Space Shuttle Endeavour successfully lands at Kennedy Space Center, completing mission STS-113.
Post-incident
GEIPAN Investigation Concludes
GEIPAN analyzes orbital tracking data, confirms ISS (object 25544) and STS-113 ground tracks match witness report perfectly. Case classified as 'A' - phenomenon perfectly identified.

04 Analyst Notes -- AI Processed
This case exemplifies the importance of cross-referencing sighting reports with known aerospace activity. The witnesses' description of "elongated luminous points" accurately reflects how the ISS and shuttle appear to ground observers during favorable lighting conditions—sunlight reflecting off their large solar arrays and metallic surfaces creates bright, elongated appearances. The straight-line trajectory and silent movement are entirely consistent with orbital mechanics at approximately 400km altitude.
The timing is particularly significant: STS-113 (Endeavour) had undocked from ISS on December 2, 2002, after Mission Specialist John Herrington completed the mission's third and final spacewalk. During the post-undocking period, the shuttle would have been flying in close proximity to the station while conducting separation maneuvers and inspection procedures. The witnesses observed this rare configuration where both objects were visible simultaneously, tracking across the sky in formation. GEIPAN's investigation included precise orbital tracking data confirming both objects passed over the Annecy region during the reported timeframe. The absence of sound is entirely expected given the orbital altitude of approximately 400 kilometers—far beyond the range of acoustic propagation through Earth's atmosphere.

BELIEVER ANALYSIS
SKEPTIC ANALYSIS
Educational Misidentification Case
This case demonstrates how unfamiliarity with spacecraft visibility can lead to UFO reports even when mundane explanations exist. The witnesses accurately described what they saw but lacked the context to identify orbital objects. The reporting to GEIPAN was appropriate, allowing proper investigation and public education. Cases like this highlight why astronomical and aerospace knowledge is crucial for UFO investigation—many 'unexplained' sightings resolve immediately when checked against satellite tracking databases, ISS visibility predictions, and spacecraft mission schedules.
06 Verdict
ANALYST VERDICT
This case is definitively explained with 100% confidence. The sighting was the International Space Station followed by Space Shuttle STS-113 Endeavour during its return journey to Earth. The witness descriptions, timing, location, and trajectory all perfectly match the known orbital parameters of these spacecraft. GEIPAN's classification as "A" (perfectly identified phenomenon) is entirely appropriate. While this case holds no mystery, it serves valuable educational purposes: it demonstrates how legitimate aerospace activity can appear unusual to untrained observers and highlights the critical importance of checking orbital data before classifying sightings as unexplained. The case also illustrates GEIPAN's thorough investigative methodology and their willingness to definitively close cases when evidence warrants.
